I made cheesy pasta and cauliflower for dinner for ds...
cheese was pre-grated medium cheddar, best before 20 march, i opened the pack last week and it did smell stronger when i added it to the pan but didn't think anything of it but
i have just opened the second pack i have and it does not smell like the one i just fed my child, not as strong and I am crapping myself that ds will have a tummy ache tomorrow??? should i prepare myself?? 
thanks
